Comparison is made to the previous CT brain.
Geographic region of hypodensity in the right basal ganglia, insular cortex, frontal, parietal and superior temporal lobes with loss of grey-white differentiation in keeping with acute right MCA territory infarct. This produces mass-effect, with effacement of the right cerebral convexity sulci, midline shift to the left measuring 4 mm at the septum pellucidum and distortion of the right lateral ventricle. Hyperdensity in the right basal ganglia are likely reflects contrast staining from the recent angiographic procedure. No acute intracranial haemorrhage.
Impression: New acute right MCA territory infarct.
